Former New England Patriots tight end Aaron Hernandez will remain in jail until the end of his trial for alleged murder.

This, after Judge Renee P. Dupuis denied bail for Hernandez, saying the state's case is very strong and the portrayal of the former NFL star as an alleged cold blooded killer is so compelling.

This developed as investigators are probing a possible connection between Hernandez and a double murder in Boston last summer.

Earlier, Hernandez's lawyer argued that the tight end is an upstanding citizen and family man with no flight risk but the judge wasn't moved, saying the prosecution has strong evidence that will pin the football player to the killing of Odin Lloyd.

"The case against him is strong, and he would be looking at a chance of life in prison without parole," assistant district attorney William McCauley said during the hearing.

Hernandez's fiancee -- who was also present in court -- was inconsolable when the judge issued her decision to keep Hernandez behind bars.

Meanwhile, McCauley informed the judge that police last night searched a Franklin condominium that Hernandez is renting, and a variety of ammunition was found in that condominium.

"Yesterday's search warrants that found three boxes of .45 caliber ammunition and ammunition for a rifle," McCauley said.

Authorities also searched a Hummer registered to Hernandez at that condominium's address, and they found a clip for a .45 caliber firearm.

Meanwhile, authorities will be back at the Hernandez's North Attleboro home to look for possible evidence in connection with a double-murder July 15 of last year in the South End.

On July 15 last year, police were called to that intersection for a report of two "persons shot", the Boston police blog states.

Upon arrival, police reported finding two men dead at the scene -- Daniel Jorge Correia de Abreau, 29, and Safiro Teixeira Furtado, 28, both of Dorchester.

Patriots tight end Aaron Hernandez arrested, released by team

North Attleborough, MA

New England Patriots tight end Aaron Hernandez was arrested Wednesday morning, just a week after an acquaintance of his was found dead near the player's house in an industrial park.

The specific charges for the arrest were not released by police, and Hernandez was let go by the team just two hours later.

The Patriots announced the move via twitter and shortly after through a statement.

"A young man was murdered last week and we extend our sympathies to the family and friends who mourn his loss," the Patriots' statement said. "Words cannot express the disappointment we feel knowing that one of our players was arrested as a result of this investigation. We realize that law enforcement investigations into this matter are ongoing. We support their efforts and respect the process. At this time, we believe this transaction is simply the right thing to do."

Hernandez attorney Michael Fee issued this statement late Monday:

"Over the past week, our client, Aaron Hernandez, has been the subject of a relentless flood of rumors, misinformation, and false reports in the media. These include the repeated publication of a supposedly confirmed report that an arrest warrant had been issued for Aaron, a report that was exposed as untrue.

"None of these false reports come from official sources and we appreciate the professionalism and restraint shown by the Bristol County District Attorney's Office to date with regard to its public statements while its investigation is underway. Out of respect for that ongoing investigation, we will continue to refrain from commenting on its substance."

Hernandez was given a five-year, $40 million contract last summer and is coming off a season in which he collected 51 catches for 483 yards and five touchdowns.
